Your AI assistant isn't only assisting you... 🤖 In the past, when an account got compromised, attackers would start enumerating what they could reach. This process would not only take time but also leave a trail of access events that virtually any SOC could catch. But now, enterprise AI assistants do that work for them. For example, Microsoft 365 Copilot inherits the permissions of the currently logged-in user. An attacker can simply prompt the assistant, "Show me the most recent financial reports," without having to dig through SharePoint or OneDrive. Attacker activity is also condensed into a single query through Copilot, making it harder for forensics teams to use legacy monitoring rules. With Varonis Atlas, organizations can understand how AI is used, detect anomalous behavior, and investigate incidents with full execution context across models, agents, and tools. It goes beyond chat logs and model outputs and dives into prompts, responses, data access, and more. 

Bye-bye shadow AI. 🔦 AI is being adopted by organizations faster than security teams can review and approve, leaving them in the dark and potentially putting sensitive data at risk. That's where Varonis Atlas steps in. Varonis Atlas provides continuous discovery of all AI systems across the enterprise. It goes beyond LLM endpoints and chat apps. Atlas inventories everything from MCP servers to models and agents. And then it takes it a step further. Discovered AI assets are tied to users, data access, and activity context, making shadow AI immediately actionable instead of just visible. Atlas builds a living inventory that shows what AI is being used, how it's connected, what data it can access, and what actions it can take. It's your organization's fastest path to safe and trustworthy AI. It's time to shine a light on shadow AI, learn more here: https://lnkd.in/ezquxwSq

Over 99%. 💫 That's how much of Webster Bank's data is safe, secure, and protected because of Varonis. When it comes to banking data, there's no room for error. That's why Webster Bank chose Varonis to bring them the visibility and security they needed. Varonis secured millions of files in its shared drive, bringing the total percentage of insecure files to less than 1%. Today, we not only help keep their data safe but also help their organization safely adopt AI by providing monitoring and oversight of their Copilot environments as they continue to grow. 

Excellent AI security is founded on excellent data security. Organizations are rushing to integrate and benefit from AI faster than ever. Unfortunately, so are threat actors. The widespread adoption of AI has put immense pressure on security teams to understand and secure the data produced and accessed by AI. The complexity and scale of AI usage require an equally fast and comprehensive security system to keep up. Organizations deserve a system that provides safety and security without slowing down. Varonis Atlas provides organizations with the fastest path to trustworthy, secure AI. Learn more about Varonis Atlas here: https://lnkd.in/dZCVrqhm

What feature of Model Context Protocol (MCP) can make security teams nervous? 🧐 Flexibility. MCP was designed to standardize how AI agents discover tools, retrieve context, and take action, making it easier to connect to real systems. But this flexibility can come with a risk. Without sufficient guardrails in place, MCP can combine access, reasoning, and execution to cause serious security concerns. Here are two strategies security teams can use to keep MCP safe and secure: ✅ Define clear trust boundaries and checks for MCP: Apply least privilege and scope the MCP server to a clear domain. ✅ Protect MCP inside AI systems: Continuous monitoring and runtime controls can mitigate risk without sacrificing speed and innovation. Varonis Atlas operationalizes Zero Trust by treating everything agentic AI does as something to be continuously verified, enforced, and observed.
